Earthquakes often occur along plate boundaries, when sudden movements of the "stuck" plates release elastic strain energy, sending out seismic waves that result in the ground shaking familiar to many worldwide. More rarely, ...
The Hikurangi Margin, located off the east coast of the North Island of New Zealand, is where the Pacific tectonic plate dives underneath the Australian tectonic plate, in what scientists call a subduction zone. This interface ...

Seismologists have known for years that the Indo-Australian plate of Earth's crust is slowly breaking apart, but they saw it in action last April when at least four faults broke in a magnitude-8.7 earthquake that may be the ...

Scientists have recreated the extreme conditions at the boundary between Earth's core and its mantle, 2,900 km beneath the surface. Using the world's most brilliant beam of X-rays, they probed speck-sized samples of rock ...

A new theory developed at Purdue University may solve the mystery of why the New Madrid fault, which lies in the middle of the continent and not along a tectonic plate boundary, produces large earthquakes such as the ones ...

The 2007 Solomon Island earthquake may point to previously unknown increased earthquake and tsunami risks because of the unusual tectonic plate geography and the sudden change in direction of the earthquake, according to ...

Temperature and shear stress are two influential variables that affect faulting and seismicity in subduction zones, where tectonic plates converge. Yet because earthquakes originate tens of kilometers below Earth's surface ...

Rocks once buried deep in ancient subduction zones—where tectonic plates collide—could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research ...
